*4.1. Film-Formation*

*4.1. Film-Formation* SA and AG were provided by Sisco Research Laboratories (SRL), Mumbai, India. 1.5% (*w*/*v*) solution of SA and a 0.5% (*w*/*v*) solution of AG were prepared separately by dissolving the polymers in distilled water and stirring them overnight for complete solubilization at the magnetic stirrer. After complete solubilization, both solutions were subjected to mixing with the gradual addition of 1% glycerol (BDH Laboratory, London, England) as a plasticizer. The resultant solution was subjected to stirring for 3 h at a magnetic stirrer. The obtained film-forming solution was divided equally into four beakers and labelled as AC-1, AC-2, AC-3, and AC-4. Subsequently, different concentrations (15 μL, 20 μL and 30 μL) of the CEO (Nature Natural, Ghaziabad, India) were added to AC-2, AC-3, and AC-4 samples, respectively, while the AC-1 sample without the addition of the CEO was used as a control sample. Additionally, different concentrations of 30 μL, 40 μL, and 80 μL of tween 80 (Sisco Research Laboratories, Mumbi, India) were also added as a surfactant to AC-2, AC-3, and AC-4 samples, respectively, for the uniform dispersion of oil in the film-forming solution. The obtained solutions were poured onto the labelled petri plates and left to dry for 48 h at room temperature. After drying, the films were evaluated SA and AG were provided by Sisco Research Laboratories (SRL), Mumbai, India. 1.5% (*w*/*v*) solution of SA and a 0.5% (*w*/*v*) solution of AG were prepared separately by dissolving the polymers in distilled water and stirring them overnight for complete solubilization at the magnetic stirrer.

The obtained solutions were poured onto the labelled petri plates and left to dry for 48 h at room temperature. After drying, the films were evaluated visually and subjected to further examination.
